The Interrupt Edge Select (IRQES) register (Table 44) determines whether an interrupt is
generated for the rising edge or falling edge on the selected GPIO Port A or Port D input
pin.
IESx—Interrupt Edge Select x
0 = An interrupt request is generated on the falling edge of the PAx input or PDx.
1 = An interrupt request is generated on the rising edge of the PAx input PDx.
where x indicates the specific GPIO Port pin number (0 through 7).
The Shared Interrupt Select (IRQSS) register (Table 45) determines the source of the
PADxS interrupts. The Shared Interrupt Select register (Table 45) selects between Port A
and alternate sources for the individual interrupts.
